Home — which will be available as a download from Google’s Play Store — is viewed as a Facebook takeover of Android and a significant threat to Google, as it puts Facebook’s updates, contacts, messaging service, photos and soon, more invasive advertising, directly on to your phone’s lock screen and home screen.

Almost as soon as Home was announced some users worried that their calls, text messages, location and data from other apps would all be hoovered up. A lot of this data — including location, contacts and calls — Facebook already has access to if you use its existing Android app, while Facebook Messenger asks for permission to read your SMS and MMS.
